( r In Fig. thegratingwhich is usually installed in the refrigeratingsectionsis shown only-in cross section, this grating in, prac-. ticebeing duplicated at the other end. ofthe car. In the interest ofclear-mess. however, the grating is notshown infFigs. 1, 2.;and

4, because; if illustrated, the grating which; is notva part of my nventon wouldycover up the construction. pertaining to. the invention hereinCllSClOSGd and claimed.

In the drawlng, A- represents the usual ner wall, D the heat insulation,E the stanchionsor posts, F the shoes for supporting the stanchio ns, Gthe supporting beams for the gratin'g'har-s H; I are the drainsincthere-o rigerator ends otthecar-and Kthe flooring in the main body of thecar, all of which are of the usual construction and conventionally shownand well understood by those skilled in this art.

1 In thedrawing, is a composition floor covering made preferably of amixture of high grade asphalt and very fine sand, the said compositionbeing laid on top of the flooring in the main body of the car and on thetop of the insulation in the refrigerator ends of the car. This floorcovering composition is preferably approximately 1 inch in thickness andit extends upwardly at the ends and sides of the car for a distance ofapproximately 3 inches.

In laying the surface flooring strips of' wood 20 and 21, each beingtriangular in horizontal cross section, are secured on the insulationbelow the ice-boxes in the longi tudinal cornersbetween the insulationand the inner walls of the carby means of spikes 22 driven through thestrips and into the lIlSLllEItlGll, the strips being positioned at adistance of about ..,-th of an inch in width from the side walls of thecar. Similar strips and 31 run longitudinally of the car from ice-boa:bulkhead to ice box bulkhead. eXce t for the s aces necessar P Tl larstrips 30 and 31 and the inner walls of the car.

Across each end of the car a triangular strip of wood 35 is secured (oneonly being shown). This strip borders the end of the walls formedunderneath thegrating of the ice-box. The composition isthen laid overthe floor of the main body of the car and over the insulation underneaththe ice-boxes at a thickness of approximately 1 inch, and it is,extended upwardly over the hypothenuse of the triangular strips 20, 21,30 and 31 for a distance of 3 inches. but does not contact with the sidewalls and end corner strips 35 of the car, the open space between thembeing about inch in width. Each of these spaces or crevices is filledwith a bituminous binder designated at 40, 41 and i 42, which binder,because of its resiliency.

will give when the parts of the car are caused I to vibrate to and fromeach other when the car is in motion and thus will always providea'hermetical seal between the edges of the strips and the edges of thecomposition flooring and the sides and ends of the car. So also, in thespaces about Q, inch wide,

formed around the drains, a bituminous binder 43 and 44 is poured sothat in the event of movement of the drains with respect I to thecomposition flooring, the bituminous binder will always remain intactand prevent crackage between the composition flooring and the drains.Also the bituminous binderfills the spaces 43, 44, 45, 46 and 47 formedbetween the edge of the composition flooring and the metal supports forthe stanchion of the ice-box bulkheads, likewise to prevent crevicesbeing formed therebetween, so that water and other matter will not oozefrom the surface of the composition down to the flooring or theinsulation. The widths of these spaces are about I inch.

At the junction of the side flanges of the composition formed entirelyaround the car,

layers o'fbituminous binder 50, 51 and 52 are placed, this being also ofa resilient character so that at the corners where the strains andstresses are great the binder will not crack and will thus form asurface at the corners which will always remain intact,

thus preventing water from the melting ice and material from the freightwhich is tionat 200 gram at 32 degrees F. 18, the

specific gravity 1.01.

Referring more particularly to Figs. 1 and 5, the door openings areindicated at O, the sides of which are preferably lined with sheet metaland 71, the sills being reinforced by metal plates 72 and '78. Just inside of the door opening are placed metal plates 74 and 7 5 which extendthe width of the door and project inside a short distance, as clearlyshown, to protect the sloping edges 76 and 77 of the composition at thedoors from undue wear occasioned by the trucks which are frequently usedwhen loading or unloading thecar.

As changes of constructions could be made withinthe scope ofmyinvention, it is intended that all matter contained in the abovedescription or shown in the accompanying drawings be interpreted asillustrative and not in a limiting sense.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is r 1. In a railway car, the combination ofwalls. a supporting floor, strips on said floor having one face slightlyspacedfrom said walls, a hard, waterproof layer on said floor extendingupwardly on said strips to provide a narrow space between the edge ofsaid layer and said walls, and a resilient filler in said space betweensaid walls and said strip and the adjacent edges of said layer. s

2. In-a railway car, the combination of walls, a supporting floor,strips of trianguwaterproof surface layer on said floor ex tendingupwardly on said strips to provide a narrow space between the edge ofsaid layer and said walls, and a bituminous binder in said space betweensaid walls and said strip and the adjacent edges of said layer.

4; In a railway car, the combination of a hard, waterproof floor surfacelayer having upwardly inclined edge portions, a flat supporting surfacefor said layer inclined v slightly upwardly toward the walls of said carto support said upwardly inclined portions of said layer, and aresilient filler between and separating the walls of said car from theedges of said layer.

5.'In a railway car,'the combination of walls, a flat floor having itsedge portions inclined upwardly, a hard, waterproof surface layercovering said floor and said upwardly inclined edge portions, and aresili-' surface layer from said i angle between the flat and theupwardly inclined portions.

7. In combination with a hard, water proof car floor covering comprisinga body car floor covering comprising a body por-,

tion and an upwardly inclined side flanged portion, a bituminous bindercovering the junction of said body and flanged portions, car walls, anda bituminous binder between and separating the edge of said floorcovering from said walls. 9. In a refrigerator railway car, thecombination of inner walls, heat insulating flooring, strips secured tosaid flooring and spaced from said inner walls, a hard, waterproof floorcovering on said flooring and strips having its side edges spaced fromsaid inner walls, and a bituminous binder in the space between saidstrips and walls and between said floor covering and walls to preventthe formation of cracks thereby preventing moisture on the floorcovering from, reaching said flooring. 10. In a railway car, thecombination of walls, a supporting flooring, a floor of asphalt and sandcomposition having its edges slightly spaced from the inner surface ofsaidiwalls, and a filling of resilient material impervious'to moisturein the space betwee said walls and floor.

11. In a car having a floor and stanchions extending downwardly andsupported on said floor, a hard, waterproof surface layer on said floorand slightly spaced from said stanchions, and a bituminous binderfillingthespace between said floor and stanchions to provide aliquid-tight sealtherebetween.
